在水稻移栽后遭受洪涝的机插秧田块,开展不同淹水时间稻田中后期喷施硅肥的肥效试验。结果表明,机插稻遭涝灾后中后期配施“硅丰壹号”硅肥有利于增强抗逆能力,促进成熟期叶片光合产物积累,增加产量,以处理4,即喷施4次硅肥,每次用量为200 g/667 m2的处理产量最高。
A field experiment was carried out to explore the effects of different silicon fertilizer management on machine transplanting rice after water-logging. The results showed that application of silicon fertilizer could improve the resistance and increase the yield of rice, the yields of treatment 4 were higher than the others. The comprehensive effect showed treatment 4 > treatment 3 > treatment 2 > treatment 1 > treatment 5.
